(under subclass 53) Subject matter wherein a plurality of amplifier devices are in a system having a single source and load, include a delay line coupling (which may be a distributed parameter line, or an artificial line) and wherein the inputs or outputs of such amplifier devices are coupled to such delay line means at phase displaced points.
(1) Note. Push-pull amplifiers including delay line coupling, per se, are not classified in this subclass but in subclass 55 below.
